Question

In triangle XYZ, the measure of Angle x is 30° greater than the measure of Angle y and angle z is a right angle. Find measure of y​

Answer 1

Answer:

30 degrees

Step-by-step explanation:

let y = a

x=30+a

z=90

sum of all angles in a triangle =180

a+30+a+90=180

a+30+a=180-90

a+30+a=90

2a+30=90

2a=90-30

2a=60

a=60/2

a=30

angle y= 30 degrees
